An air carrier B727 flight crew became involved in checking their relative position to an airway and did not monitor the leveloff. Also, the captain admitted that he did not arm the altitude capture mode. They overshot and then rapidly corrected.

Narrative:
Climbing to 27000 ft, controller questioned our position on the airway. During discussion of aircraft position, altitude capture did not occur resulting in deviation of 600 ft high. I thought I had altitude capture armed, but apparently it had not been engaged. While checking on our position, per controller request, all 3 pilots became preoccupied with horizontal navigation and missed checking and monitoring leveloff altitude. When deviation was recognized, aircraft was corrected back to altitude.

Title: AN ACR B727 FLC BECAME INVOLVED IN CHKING THEIR RELATIVE POS TO AN AIRWAY AND DID NOT MONITOR THE LEVELOFF. ALSO, THE CAPT ADMITTED THAT HE DID NOT ARM THE ALT CAPTURE MODE. THEY OVERSHOT AND THEN RAPIDLY CORRECTED.
Narrative: CLBING TO 27000 FT, CTLR QUESTIONED OUR POS ON THE AIRWAY. DURING DISCUSSION OF ACFT POS, ALT CAPTURE DID NOT OCCUR RESULTING IN DEV OF 600 FT HIGH. I THOUGHT I HAD ALT CAPTURE ARMED, BUT APPARENTLY IT HAD NOT BEEN ENGAGED. WHILE CHKING ON OUR POS, PER CTLR REQUEST, ALL 3 PLTS BECAME PREOCCUPIED WITH HORIZ NAV AND MISSED CHKING AND MONITORING LEVELOFF ALT. WHEN DEV WAS RECOGNIZED, ACFT WAS CORRECTED BACK TO ALT.
